Ovulation

So, I know this app isn’t very accurate all the time. I took a ovulation test and the second line is a little lighter. (Got it from the dollar tree: don’t know if there that accurate) But the app says I’ll ovulate on the 23rd. But, right now My back hurts, I have a headache, bloated, and my boobs are alittle sore. Could I be ovulating now?
